To all whom it may concern: i Y

Beit knownthat LKARL L. MAYERS, citizen of the United States, and resident of St.

Louis, Missouri, have invented certain new and useful Improvementsgin` Syringes,V ofl for flushing and washing the vagina, retaining the fluid therein, and to remove the fluid by suction created by a bellows.

In the drawings-.Figure 1 is a perspective view of my complete invention. Fig. 2 is a central sectional View ofthe same.` Fig. 3 is a cross sectional view taken on the line `3 3 of Fi 2. tiona view of the spray end of the syringe.

In the construction of my invention I provide an outer tube 5 having anl outwardly tapering ortion 6, its end 7 provided with an interna screw-threaded openingS in which is inserted an external screw-threadedbushing 9. The tapering portion 'is provided with a nipple 10 to which'is attached a hose or tube 11 to admit fluidinto the tube v5 from a fountain reservoir 12 or faucet 13.

The outer end 141is provided with an internal flange 15 whichA has a tendency to direct the fluid inwardly against an linner tube ldcontacting with the under surfaceof the flange 17 formed thereon and directing the fluid outwardly forming a globular spray as shown in Fig. l and by dotted lines in Fig. 4. The inner tube 16 extends through the tube 5 and is provided with external screw-threads 18 which engage with internal threads formed in the bushing 9. The end 19 of said tube '16 is provided with a flange 20; between the same andthe bushing is firmly* held a bellows 21, by which the fluid is extracted from the vagina by suctioncaused by expanding the Fig. 4 is an enlarged detail secf bellows. This is accomplished by pulling upon the eye 22 secured to the end 23 of the bellows. 1 Y

`The bellows 21 is formed preferably of rubber; Vthe section connected to the tubes vis of a `thicker material than the portion to be extended. `By this construction the bellows can be more easily manipulated than where both sections are of the same thickness. `The bellows is absolutely leak-proof,

1 `and contains the fluid removed from the vagina and the same isemptied by inverting the syringe, holding the same with the tube `end downward. The tube 16 is properly v spaced in the outer tube 5 by lugs 24 formed integral with the inner tube. (See Fig. 3.) Upon the outer tube 5, immediately at the intersection of said tube and tapering portion 6, I place a` shield -25 which is of sufficient size and flexible material to close the passage to retain the iiuid in the vagina while sprayin In using my device, and in instances ,where the patient wishes only to cleanse the vagina by ushing it 4with Water, the hose 11 is attached to the faucet of a hydrant as shown by dotted lines in Fig. 1, but in instances where hydrant ressure is not avail- -a'ble,ror in instances w ere the patient deyslres to usean antlsep 1c fluid preparatlon,

the vreservoir 12 is use which consists of an air-tight receptacle provided with an inlet 26,

and pressure is im arted upon the fluid by means of the air bu b 27.

V With the use of my syringe the entire wall of the vagina is thoroughly washed, the contents remaining in the vagina while being `washed and thenremoved by expanding the bellows into which the fluid is conveyed.

Having fully described my invention, what I claimis: p i.

, A syringe comprising an inner tube; a flange formed on the end ofthe inner tube; lugs formed on the inner tube; an outer tube;

` an inwardly projecting flange formed on the end of the said outer tube and located directlybeneath the flange of the inner tube so as to deect the liquid, forming a globular spray, `the said lugs on'the inner tube contaoting with the inner surface of the outer prooi` connection; a shield located upon the 10 tube to hold the inner tube in central posiouter tube, substantially as specified. tion7 the said outer tube having a ta ered In testimony whereof, I have signed my portion; a nipple formed on the tapere pornalne to this speoiiioation, in presence of two 5 tion for the admission of the liquid; a belsubscribing witnesses.
